I assume you are talking about the lease on your apartment?
I know you said money was tight, however, if you ask her what is next for the two of you....b/c you need to know what to do about the lease, that gives her 100% control and it makes you look very weak in the eyes of the WAW. I don't mean that in an offensive way and I can sympathize with the money issue, but the mind of a WAW can be very different than that of a LBH. Even though your W is not talking favorable about having a future with you, the least thing that makes you appear to be needy can really be a huge turn-off to her. I don't know if you ever discussed your financial circumstances with her or not, but she surey knows what it is! She knows what you are giving her every month and how much your salary is, so she should realize how tight things are for you.
I think you were asked by another poster if you could move back into your home, but I can't remember how you responded to that. Just as a way of throwing some ideas around....what would happen if by the end of December you told her you could no longer afford to pay her and pay for the lease on your apartment....therefore you would be moving back into your house.
Since she was the one who did not want to remain in the M....she can find a place to live if she doesn't want to stay with you. That is giving her a two weeks notice....right?
BTW, when you do move back into your home....be sure to take back your marital bed. If she doesn't like it, tough. She can find some place else to sleep. Oh, she'll have a fit when you start to put your things into her room and when she asks what you're doing, you calmly tell her you are moving into your bedroom. You will have to stand tall b/c she's going to show you what she's made of. What can she do about it anyway?
Unless there is some weird law there that would keep you out of your home, then I don't know how she could stop you from moving back.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
